[Qemu-block] [PATCH v2 0/4] iotests: Emit signal-kill messages

[Max Reitz]

Currently, if a qemu-related command (qemu, qemu-io, qemu-img, qemu-nbd)
is invoked in an iotest, receives a signal and is subsequently killed
(e.g. a segmentation fault), this is not logged in the test output. The
first patch in this series makes the bash tests no longer suppress that
line, and the second patch adds a similar notification for the python
tests.

Patch 3 tries to fix some handling of spaces in command filenames, and
apparently actually succeeds in doing so (all Python tests work, most
bash tests work; if they fail, it's the test's fault). However, it does
not fix handling of spaces in arguments: This is because we probably
don't have to worry about that anyway, and because it would be pretty
difficult to fix.


v2:
- Patch 1: Added, pulled in from v4 of my "blockdev: BlockBackend and
  media" series (needed in patch 2)
- Patch 2: Added, required because patch 3 now fixes argument handling
  for the Python iotests
- Patch 3:
  - Fix handling of spaces in command filenames [Jeff]
  - Fix argument handling for Python iotests (accidental fallout from
    the above)

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
